REVERE — When Wonderland Ballroom was in danger of being turned into an MBTA parking lot in 1986, ballroom dance enthusiasts wrote letters, distributed pamphlets, and jammed State House phone lines — saving the beloved dance hall from the wrecking ball. But today, with the ballroom on the verge of being demolished and turned into a hotel, no one is rising up to stop it.

The days when the Wonderland dance floors were crowded with waltzing couples are long gone. The ballrooms that once lined Revere Beach, and served as social gathering spots throughout the region, have been closed or relegated to function hall status.

“It’s the end of an era,” said Wonderland owner Robert Merowitz, who is looking to sell the Wonderland property to a hotel developer.
